My plants are 3 years old (counting from soaking the seeds) and they are growing really fast but the leaves are a little bit yellowish in the middle. Is this some kind of deficiency or maybe something else? I’m a newbie to this and need your help guys ;)
@Techgrower 3 years old!!! 😂 I'm thinking you meant 3 weeks? Looks like they could do with a comprehensive feed containing NPK mag cal iron etc
basically anything suited for growing @ half strength for now should do
